The Yuma Crossing National Heritage Area App provides a self-guided tour of the Colorado River State Historic Park, more commonly known as the QuarterMaster Depot. The exhibits at the park cover 2 different time periods, from the original use in the 1870s as the QuarterMaster Depot, to the later use in the 1920s by the Bureau of Reclamation. Audio recordings tell the stories of the two time periods, similar to the presentation you would get from a tour guide.
